A Guide to Interior Finish Options for Pre-Engineered Metal Buildings
When most people think of pre-engineered metal buildings (PEMBs), they imagine the strong steel framework and durable exterior panels. But what goes on inside is just as important. Interior finishes influence the look, comfort, performance, and even the energy efficiency of your building. At FED, we know that not every customer is an expert in metal building systems, and that’s okay. Our role is to guide you through the options, explain the pros and cons, and help determine the right finish for your building’s purpose, budget, and long-term performance goals.
Below are the four most common interior finish options for PEMBs, each offering unique advantages.
1. Metal Liner Paneling
Best for: Durability, clean aesthetic, impact resistance
Metal liner panels are steel sheets installed along the inside walls or ceilings of a PEMB. They create a bright, clean surface that is easy to maintain and extremely durable.
Cons: Slightly higher upfront cost than insulation-only options
Pros: Impact-resistant, easy to wash down, professional finished look
FED Example: On our Stoops project, we used metal liner panels on the ceiling of the wash bay for energy performance, easy maintenance, and a clean appearance.
2. Simple Saver® Fabric System
Best for: High R-values, energy efficiency, large clear-span buildings
This system uses a fabric liner stretched across the inside of the structure with thick layers of insulation behind it. It creates a bright, white ceiling or wall surface while significantly improving thermal performance.
- Pros: High insulation values (R-25+), reduces condensation, bright reflective finish
- Cons: Not as impact-resistant as steel liner panels
FED Example: Our R&B Electronics project utilizes this system creating a bright energy efficient finish.
Often, the right interior finish is a blend of different options depending on the intended building use.
Our RE Glancy Project paired Simply Saver walls and ceilings with metal liner paneling on the bottom sections of their walls to add durability without sacrificing high R-value.
3. Insulated Metal Panels (IMPs)
Best for: Energy efficiency with a sleek, modern appearance
IMPs are composite panels with an insulating core sandwiched between two steel skins. They provide both structure and finish in one product, delivering excellent thermal performance and a smooth, uniform appearance.
Cons: Higher cost compared to other finishes
Pros: Excellent insulation (Available in R-60+), fast installation, attractive modern aesthetic
FED Example: At our Clare Gladwin RESD project, IMP walls provided a polished interior look with energy efficiency built right in.
4. Faced Insulation with Vapor Barrier
Best for: Storage buildings, budget-conscious projects
This option places fiberglass batt insulation between the steel panel and the building’s framing, then covers it with a vapor barrier (often a white facing). It’s a straightforward, economical way to manage condensation and improve comfort.
Cons: Lower R-value than other systems, not as polished in appearance
Pros: Affordable, reduces noise, prevents condensation
FED Example: Our East Jordan Plastics project used this system in the roof, where a white vapor barrier provided a clean, functional finish.
Choosing the Right System
The right interior finish depends on how your building will be used. A storage warehouse may not need the same level of finish or insulation as a recreation facility, manufacturing plant, or office space. Metal liner panels can be combined with other systems for added durability, while IMPs offer a sleek all-in-one solution.
Our team takes great care in helping you weigh performance, appearance, and budget. With decades of experience across all four systems, we’re here to ensure your building interior is functional, efficient, and exactly what you envisioned.
Whether you need a durable finish for a high-traffic space, an economical solution for storage, or a high-performance system for comfort and efficiency, FED can help you select the best option. Contact us today to discuss your project and explore real examples of these finishes in action.
